Using Basic Powershell Commands

  1. How to Run Powershell Picture 16How to Run Powershell Picture 16
    Use 'Get-Command' to find cmdlets. On its own, this cmdlet will display all other cmdlets. You can narrow your search using modifiers.
    1. For example: 'Get-Command Name *Disable*' will display only cmdlets with 'disable' in the name.
    2. All cmdlets are entered by typing them into the Powershell window and hitting ↵ Enter.
  2. How to Run Powershell Picture 17How to Run Powershell Picture 17
    Use 'Get-Help' to get info on a certain cmdlet. This cmdlet will give you all the information regarding another cmdlet, most importantly syntax for how the target cmdlet is used.
    1. For example: 'Get-Help Get-Process' will display all the usable information for the 'Get-Process' cmdlet.
  3. How to Run Powershell Picture 18How to Run Powershell Picture 18
    Use 'Get-Process' to use a process running on a computer. Alone this will display a full list of processes running on your computer. With a modifier, you can single out processes coming from a specific application.
    1. For example: 'Get-Process winword' will display all processes being run by Microsoft Word.
    2. Similarly, 'Start-Process' can be used to launch an instance of an application/process.
  4. How to Run Powershell Picture 19How to Run Powershell Picture 19
    Use 'Get-Member' to see properties or methods of an object. This cmdlet needs an object 'piped' to it in order to be useful. This is done by adding a '|' between an object and the 'Get-Member' cmdlet.
    1. For example: 'Get-Process | Get-Member' will pipe the Get-Process cmdlet to Get-Member, and Get-Member will list all of the properties and methods you can utilize when scripting with Get-Process.
  5. How to Run Powershell Picture 20How to Run Powershell Picture 20
    Use 'Where-Object' to select objects based on criteria. The criteria in Where-Object is set by using the following formatting: '{$_[object] [operator] [parameter] }'. Where-Object also needs an object piped to it.
    1. For example: 'Get-Process | Where-Object { $_.name -eq 'notepad' }' will run Get-Process with the limitation where the object's name is equal to 'notepad'.
    2. Other operators include: '-lt' (less than), '-gt' (greater than), '-le' (less than or equal to), '-ge' (greater than or equal to), '-ne' (not equal to), or '-like' (pattern matching).[2]
    3. Parameters using strings (words) must be enclosed in quotations marks. This is not necessary for integers (numbers).
